Preheat oven to 300 degrees.
Add coconut oil and maple to a microwave-safe bowl. Microwave on half power until the coconut oil is melted.
In a large bowl, combine the oats, pecans and coconut. Pour the coconut oil and maple over the oat mixture. Add egg white, if using. Toss well to combine.
Spread the uncooked granola in a single layer onto a parchment- or silicone-lined baking sheet. Bake for 45 minutes, or until golden brown.
When the granola is cooled (and hardened), break it up into pieces and toss with the mini chocolate chips.
Store in an airtight container at room temperature for up to 2 weeks.
